Purpose: Find the relationship between time and distance.

Data: (Place your data into the table for your class.)

Table 1-3: Individual data from hallway: Block number:

Trial # vs. Time

Average Time:

Table 4- Class data -

Distance (block) vs. Time

Graphs -3 graphs - Med - North , Fast-North and Slow-South

Write equations (mathematical models) for the three individual graphs.

Calculations - Title each calculation, show the formula and the work for ONE calculation.

I. Show one calculation of average time from your trials.

2. Show conversion from blocks to meters. (1 block on diagonal = 105 cm)

3. Calculate slope from one of the slopes of your line (velocity) derived from computer.

Bonus - What is the relationship (formula) between the number of books used to hold up the ramp and the speed of the ball? (Hint - make a graph)

Questions -

1. How is making a graph on computer different from a hand made graph? Which do you like better?

2. What does the slope of the graph represent?

3. What does the sign of the slope represent?

4. What does the y-intercept mean?
